Google “2212-kv920 thrust test” I get, From https://www.rcgroups.com/forums/showthread.php?2266912-DJI-E300-(2212-920KV)-Motor-Prop-Testing, Motor: DJI E300 (2212/920Kv) – Page 1 of 4, Prop: iFlight iCF 8055 Carbon Fiber DJI Hub (TE Style blade) I found myself flying only the bottom 1/3rd of the stick almost exclusively, so I added some negative curve. 50% 16.36 2.72 45 6270 333 80/27 So there is no way to use Kv to tell you how powerful your motor is. (This post was last modified: 30-Dec-2019, 10:28 PM by, https://brotherhobby.com/avenger-2810-mo...172p1.html, https://brotherhobby.com/avenger-28065-m...132p1.html, Katana-LR4 (Long Range 4 inch) My 4th Build. 50% 12.36 2.05 25 4892 210 72/22 So that motor power can be calculated. The highest performing quads have the best power to weight ratios. By the way, at the point “Torque & it’s relationship to kv” you wrote that kv is the inverse of kt. The correct way to think about Kv is to think of it as a motor constant. 25% 12.37 0.93 12 3067 106 77/25 So a motor with higher torque will be easier to tune, and will make the quad feel more precise in the air. A lighter motor will most likely feel more precise in the air, and pids might be easier to tune. Replaces motor mount cross and brings motor further back. Fits for motors with 16x19 spacing (like 220X and 230X), 16x16 spacings (Like AriB 2514) and 19x19 spacings. This is important not only to keep our special 2-in-1 ESCs happy, but also to protect the battery. 3S (12.3V) You will need less thrust/motor if you have more motors, but it all comes down to motor/prop thrust values vs. overall weight of your Hex. So let’s use them as an example. Throttle Volts Amps Watts RPM Thrust(g) Winding Temp (F/C) can you help me do deside witch motor should I use? I've been getting into some long range (technically really short long range atm) and trying to figure out a good balance between prop size for 7 inch and motor sizes. Two complaints, you use “WOT” without defining it. You simply need to determine the current draw from the motor/prop combo and then make sure that your ESC and battery can handle the current demand of the combo. 4S and up ofc. If i want to use 10000 kv moter then which esc i should purchase and which battery. for example how much weight can a 250mm drone frame size, 2300KV Brushless Motors and 30A Esc can lift? We have even used locknuts on 3D setups without issue. Motors handle about one quarter of the current from the battery. Stator size effects the torque output, and larger stators tend to produce more torque, whereas smaller stators produce less.”. My project does not involve any flying. 50% 16.32 2.83 46 6271 297 72/22 This means that when a motor spins, it creates back-emf that can be measured as voltage. Drones. Here are some more build pics of the freestyle project. 100% 15.88 13.58 216 9596 1034 125/52. I have builded test stand for my project at university. 25% 12.34 0.60 10 4424 49 70/21 First of all many thanks to you for such a great blog. 3S (12.3V) Required rpm values range from 50 to 300 (or 60, 90, 120, 180, 240 and 300) which do not need to be achieved quickly. Therefore, the first thing to consider when choosing the right setup is to determine what size drone you want to you want to build, what size props your chosen frame can run, and what batteries you want to use. We here at QQ have found the following to be a good starting guide for sizing stators to propeller size: Selecting the right motor comes down to weight, power, efficiency and torque and the importance of each of these are ultimately determined by your flying style and what you are trying to accomplish with your multi-rotor build. I’m thinking along with your specs. I like how you say that you need to consider your frame type when you are choosing a drone. How to calculate the motor current if battery current is known. Although, beyond the scope of this post, I will only point out that the popularity of the 5x4x3 has to do with the fact that it is a very well balanced prop in terms of thrust, rpm and speed. KV can help us understand the current requirements of a motor to produce a certain amount of torque…. R Series Outrunning Torque Motor. 75% 16.08 7.63 123 7812 757 81/27 On the other hand, establishing such formulas for so many movements as basis for computer simulation is not an easy task. So as Kv goes up, Kt goes down. FPV. Comment: OK for continuous use, Motor: DJI E300 (2212/920Kv) – Page 2 of 4, Prop: iFlight iCF 9047 Carbon fiber DJI Hub (DJI Style blade) The efficiency of this motor is also a little less than the purple top 2205 2300 KV. By using this combination, a 1300 75C battery which can handle 97.5A is perfect for this quad. 15mm Extended Prop Shaft allows virtually any prop with 5mm hole. Many thanks, you have made my life easy. „Clearly if you baby the quad it will be fine“ like krohsis wrote; limit the motor_output of the 2600kv motors, scale to less kv would prevent befor waisting energy, high ampdraw... next to the throttle expo kaity wrote. The idea is to measure thrust of different propellers. I assume it means “wide open throttle”. I am happy to realize similarities of movements between my project with those employed for flying drones. 100% 12.16 4.46 54 9674 323 70/21 There are some suggestions about quadcopter frame size related to Lipo as below, maybe useful for you, click the original article link to know … 100% 16.14 6.76 109 12187 541 71/22 75% 12.08 5.20 63 6283 490 71/22 Motor Stator Size. It is common to see that number double to 8:1 or more in racing quads. We will get you in … Comment: OK for continuous use, Prop: DJI 9443 Self Locking prop (plastic blades) 1 man, 105 kgs ready to fly. Ideally, you want to try to engineer your quad to efficiently fly, but also generate enough thrust without completely destroying your battery. Once this priority has been made, finding your perfect motor should be easy. Marty, did you ever get an answer for your specs? AirGear Combo Set. 2300-2500kv motors provide awesome performance and allow for use of 4S, but neither of those things are conducive to true range. Can you find any data-sheets on your hardware and post the links? The dimensions are 184×122×110 mm. 100% 15.81 13.75 217 9252 1171 125/52 8 of the biggest motors and blades you can buy attached to an aluminum frame. I find it more feasible to prove it by making a functional prototype instead. Google motor thrust test INSERT MOTOR NAME HERE. Agility: 5045 & 5045 bullnose or 5" triblades, with a mid-large high kv motor and a small 1300-1500mah high C lipo. You need to find a chart of a given motor’s Volts/rpm/Watts to make proper decisions about whether or not a motor is a good choice for your mulitrotor build. last, but not least, use the data that you find to make sure that you choose an ESC that can handle the current demand that your motor/prop combination will be requiring at WOT. The size of the motor can give you an idea about what size drone you will use with the motor. Use the chart in step 3 to pick a good stator size starting point, then find a motor that you think will work. “A lighter motor will most likely feel more precise in the air, and pids might be easier to tune.”, And than under the point “Torque” you wrote: The main advantages of Li-Ion over Pb (lead acid) batteries is their compact size, light weight (roughly weighing 1/6 25% 16.35 1.17 19 3778 174 82/28 Comment: OK for continuous use, Prop: FunToBuyOnline 8045 (white plastic, MR style blade) […] How to choose the right size motors & ESCs for your Drone, quadcopter, or Multirotor build […]. 25% 16.43 1.15 19 4285 133 80/27 why choose a taller stator over a wider stator for big props? The motor torque is proportional to the size of the stator, but the larger the stator, the heavier the motor. 25% 12.25 0.90 11 3023 104 68/20 Torque can be calculated using current and kt, the inverse of kv. So what can we learn from this? Really appreciate the advice. your article does not help. What is of the highest priority is that the 2 motors are identical but turn the 2 propellers accurately in opposite directions as synchronized mirror images, at various speeds. :(. Comment: OK for continuous use, Motor: DJI E300 (2212/920Kv) – Page 4 of 4, Prop: DJI 9443 Self Locking prop (plastic blades) Many people think that the ESC and battery ratings mean that the motor needs to handle the same current ratings, but this is wrong. Many people have asked me how to properly size your motors to your quad. 4S (16.4V) Installing an esc with a higher amp rating would be similar to installing a fatter wire to the motor,it could handle more current, at the expense of added weight. My 6 inch Rooter has 2600 motors and I can get around 3 miles out with it, with 5 inch blades. It is one of the smoothest flyers I have now. Many thanks. Hi, did you get an answer to your message. If you spin a motor, it will generate 1V at a certain RPM. Throttle Volts Amps Watts RPM Thrust(g) Winding Temp (F/C) Get it as soon as Tue, Dec 8. do you have to use 4 exact same motors on a quad copter or can i I put my typhoon h motors and my chroma motors together on to the chroma ecmboard?shorten up the wingspan s and use the typhoon h blades on both motors .? And frankly going with 25XX is fine. In the end, you will want to make sure that you have enough thrust to fly well. Throttle Volts Amps Watts RPM Thrust(g) Winding Temp (F/C) Some pilots run the thinnest motor wire they can to minimise weight. The stock receiver with stock antenna will begin to sell end of February 2018. If we look at the same graph, but at 50% throttle, we see that the efficiency goes way up. I scored 40a esc’s at 60%off and the esc’s that came with the drone was 20a. 25% 16.43 1.20 20 4202 139 78/26 QQ190 Tank V3 Racing Drone Frame Set includes camera. I am building a drone to carry 12kgs. It featured an all-black appearance, and a unique front bumper and staggered wheel design at the time considered to be available on future FPV products. 75% 12.27 2.37 29 7536 196 68/20 A higher KV motor can tend to be more efficient in the high rpm ranges, but at the expense of torque. Motor KV doesn’t tell you how powerful the motor is, or how much current it can handle, or how efficient the motor is! No, 40amp escs can handle more current than 20amp eacs, but the amount of current that your setup will draw depends on motor and prop combination more than anything else. Also, the entire article is implicitly written with the assumption of a 4S battery. Combo Pack. Which motor and blades to buy? Your frame type will determine many factors about your drone, such as what size props you can run, and what size motor you can mount. I will probably put 2206 and 2305 in the same category due to the similar stator volume. What Kv does do is help us to understand the current requirements of a motor to produce a certain amount of torque… because Kv is directly related to the torque constant. 50% 16.34 2.97 49 6162 357 78/26 Prop size ect i have a hexacopter with 10 inch props. Most of the long range guys with 7" blades go with a 25XX motor. 25% 12.42 0.93 12 3375 78 71/22 Manned Aircraft. Without going into too much detail, all that you really need to know is that the torque constant Kt is the inverse of Kv. Propellers are not used for flying but used to enable rollers mass as means of generating rotational momentum. 3S (12.3V) i was told the motors i got with the kit (2212-kv920) were battery eaters and when i got them running i dont like the sound of them and figure i will just upgrade. High kv motors require more current than lower kv motors to produce a certain amount of torque. So when selecting your motor, you should try to find a motor with a high power-to-weight ratio. 0505 (1) 0603 (3) 0605 (1) 0605 (2) 0703 (4) 0802 (8) 0807 (1) 0905 (1) Throttle Volts Amps Watts RPM Thrust(g) Winding Temp (F/C) Expect short flight times. Robot Dynamics. Current, torque and Kv are all related, Lower Kv motors require less current to spin heavy props and therefore have more torque, but loose efficiency at high rpm-Vice-versa, High Kv motors require higher currents to spin heavy props, but can run at high rpm more efficiently. I agree with Kaity, 23XX is as small as I think you should go. Its just a carrier drone with minimum maneuverability, just a normal flight from point A to Point B and come back. 25% 16.38 1.19 20 4260 139 72/22 A good pnunomic to remember is Wept- the guys that didn’t choose the correct motor for their quad build wept because they cooked their batteries. Remember, A good pnunomic to remember is Wept- the guys that followed the hype train and didn’t properly engineer their quads wept because they cooked their batteries. What it really comes down to is personal preference. ESC 30Amp Readytosky (100g) it seems geared towards quads and i see references to racing but how do i pick a motor that will pick up a small payload (camera and or sensors) and get decent flight times? 25% 16.36 1.17 19 3744 161 80/27 The ZMR 250, back when it came out, was a class called “miniquad” - with the larger 450 size crafts being just “quadcopters” Frame Size numbers, by the way, mean how much diagonal distance there is from one motor to the other. kV Rating. Only 3 left in stock - order soon.
